Deep Cycle Flooded Lead Acid Batteries require far more maintenance as they use a lot more water than "Maintenance Free Marine/Deep Cycle" or AGM's.

Not from my experience. In the post, I pointed out that the WFCO never went into trickle mode (13.2V). The constant 13.7V, even when fully charged, evaporated the water at a much faster than normal rate. Unfortunately, at the time, I never imagined the converter would not take decent care of my batteries.
Since replacing the WFCO with a PD converter, the batteries require topping off about once a year. Usually after a year, I'm about 1/4" below the ring in each cell. Proper voltages from the converter do make all the difference.
I learned about battery longevity back in the days of cars with generators and adjustable regulators. If you did all short distance driving, you wanted to set the regulator close to 14V. If you did a lot of long distance driving, 14V would boil your battery dry. Backing off the regulator to 13.6V was preferred for long drives.
just my experiences
